from Vall standpoints of manufacture and use, and while thisconstruction will be herein specifically explained, it is to beunderstood that within the scope of the invention as claimed, numerousvariations may be made.

The machine embodies a main frame M sup ported at its rear end by a liveaxle 12 and pairs of earth-packing wheels 13, at least some of whichserve to drive said axle. This main frame is supported at its front endby wheels 14 mounted upon spindles 15 whose inner ends are provided withupstanding shafts 16 mounted in a manner hereinafter described. Theshafts 16 are provided with steering arms 177 connected by front andrear transverse steering bars 18-19, with which the novel stub-tongueand hitch assembly A, is associated.

The main frame M is provided with an elevated hopper-carrying frame Triupon which may be mounted two independent hoppers 23 or a dual feedhopper 23CL as in Fig. 12, and interposed between the hoppers and saidmain frame, is a fran e P or carrying the plows 20 and lower tubesections 21 to which said plows are secured, the upper ends oi said tubesections 2l being telescopically with flexible tube sections 22 whichare connected with the seed outlets of the hoppers 23 or those of thedual feed hopper 23a upon the hopper-carrying frame H, seed droppingmechanisms communicating with the tube sections 22 being or" courseprovided. As the construction ci these dropping mechanisms forms no`part or" the present invention, they are not illustrated in detail.Parts of their casing structures however, are denoted at 24 and theirdrive shafts are shown at 25, said shaits being connected by a chain 26and sprockets. The rearrnost of the shafts 24 is driven by a chain 27from a rotary shaft 28 on the rear end oi the frame through theinstrumentality of a clutch C which will be hereinafter described. Achain 29 and appropriate sprockets are employed for connecting the shaft28 with the axle 12 so that the latter continuously drives the former.

Raising and lowering means are provided for the, -frame P, controlled bya preferably square rock shaft 30 having a hand lever 31 which may belocked in adjusted position by a pawl 32 and rack 33. This shaft isshown at the rear of the machine near the drivers seat S and it willremain at this location ir" the machine is to be horse-drawn.

The main fra-ine M embodies parallel longitudinal side bars 34 connectedat their rear ends by a transverse bar 35, connected near said rear endsby a second transverse bar 36 and connected at their front ends by atransversely disposed vertical frame V. This vertical frame is ofrectangular forni and for future reference, its top, bottom and verticalside bars are given the nurnbers 37-38-39 respectively. The lowercorners of this frame are rigidly secured to the front ends of the sidebars 34 and to attaching portions 40 of bearings 4l through which theabove inen-V frame may be of any desired construction, I wish to drawattention to the fact that it is provided with two vertical front legs46 secured to` the side bars 34 of the frame M, and with two verticalrear legs 47 secured to the transverse bar 36 of said frame M. I alsoinvite attention to the fact that the front portion of the frame H isconnected with the upper corners of the frame if by suitable ties 48.Then too, I prefer to brace the legs 46 by inclined braces 49 extendingtherefrom to the side bars 34.

The frame P embodies a horizontally elongated rectangular frame portion50 secured by appropriate clamps 51 upon two longitudinal bars 52. Thefront ends of these bars lie against the outer sides of the verticalside bars 39 of the front frame V, and by means of guides 53 preferablyembodying rollers 54, said front ends of the bars 52 are connected withsaid bars 39 so that they may slide vertically along the latter. Thebars 52 are disposed laterally of the front legs 46 of the hopper frameH and hence when the plow frame P is raised, said legs 46 form stops tolimit the lateral play of said frame P, so that excessive lashing of thelatter cannot take place. To prevent lateral shifting of this frame Pwhen it is lowered, two rigid upstanding posts 55 are secured to theside bars 34 or" the main frame M to vlie against the inner sides of thebars 52, the upper ends 56 of said posts being inclined to facilitateengagement of said bars 52 with said posts upon lowering of the frame P.

Therelongated rectangular portion 5U of the fraineP passes between thefront and rear legs 46--4'7 of the hopper frame H and embodies front andrear transverse bars 57 to which appropriate castings 58 are secured foreffecting attachment of the tube sections 21. Each casting 58 isprovided with a seat 59 for the tube section 21 and is formed in saidseat with a projection 60 for reception in an opening 61 in said tubesection as shown in Fig. 7, said tube section being held in the seat bya U-bolt or the like 62. This construction rigidly anchors the upper endof the tube section 21, and the stud 60 and opening 61 hold it againstvertical shifting and lateral twisting. The lower ends of these tubesections may be braced by any desired means such as indicated at 63 and64. l

Front and rear sets of raising and lowering cranks 65-66 are mounted onthe frame M and are connected by links 6'7-68 with the iront and rearportions respectively of the bars 52. The iront cranks 65 are mounted inbearings 69 secured to the side bars 34 (see Fig. 6), and the rearcranks 66 are similarly mounted in bearings 76 secured tosaid bars 34.These bearings 69-70 are shown to some extent in Figs. l and 2, but areiully illustrated in Pig. 5, and as above mentioned, reference may behad to Fig. 6 for the exact mounting of the cranks 65, the rear cranks Y66 being mounted in the same way. It will be seen from this View andothers that each of the cranks 65-66 is` formed with Va hub throughwhich a preferably square opening Il extends.

The shaft 30 is shown occupying these openings of the rear cranks 66 andit is so positioned when it is convenient to manipulate the lever 31 ofsaid shaft from the rear or the machine. Longitudinal links 72 connectlthe front and rear sets of cranks 65-66, so that theymust move in unil'son, regardless of which set is directly operated by the shaft 30.Cotter pins such as 73 of Fig. 6 serve to hold the hubs of the cranks65-65 within the bearings 69-70 and it will be obvious that these pinsmust pass also through openings Ile- - spring 823.

in the shaft 30, so that the later is held against endwise movement.

A longitudinal link 74 is shownpivoted at its frontend to an arm 75 onthe shaft 30 and also pivoted to a controlling arm 76 for the clutch C.Rocking of shaft in a direction to` raise the ploys, throws the clutchout of action and consequently stops the dropping of seed through thetubes 21-22. Lowering of the plows by turning of the shaft in the otherdirection however, causes re-engagement of the clutch to drive theseeddropping means. When the shaft 30 is disposed at the front of themachine, a longer link must be substituted for link 84 or Ythe lattermay be coupled to another link section to extend forwardly from it.

The clutch C is preferably of the construction detailed in Figs. 10 and11, to which viewsreference is now made. A bearing 77 is fixedly mountedin any preferred manner upon the rear bar 83 of the main fraine M, inline with one of the supporting bearings 78 for the shaft 28. This shaft28 passes loosely through the bearing 77 but a toothed end 79 on acollar 89 which is secured to said shaft 28, is rotatably received insaid bearing 77. A sprocket 81 which is engaged by the chain 27 isslidable upon the sha t 28 and is provided with a toothed hub 82, saidsprocket being urged toward the collar 80 by a coiled The inner end ofthe arm 78 is provided with an opening 84 through which the hub 82passes rotatably, vand said arm 75 is provided with cams 85 which areco-operable with additional cams 86 on the bearing 77, in eitherpermitting engagement of the toothed hub 82 with the toothed collar 89,or in preventing such engagement. When arrn 76 is moved in onedirection, the cams 85 ride from the cams 88 and spring 88 engages thetoothed hub 82 with the V toothed collar 89 so that the shaft 28 thendrives the sprocket 8l.v Swinging of arm 76 in the opposite directionhowever, causes the earns 85 to ride upon the cams 85, thereby forcingarm 7 8 laterally and causing it to so shift the sprocket 81 as todisengage the hub 82 from the toothed collar 80, whereupon shaft 28rotates freely without driving said sprocket 81.

The stub tongue and hitch assembly A will now be described in detail andreference is made more particularly to Figs. 8 and 9. 87 denotes thestub tongue pivotedat 88 to the front steering'bar 18 and pivoted at 89to the rear bar 19. This tongue 87 is provided with one longitudinalslot 90 bee tween the bars l8-19 and with a second longitudinal slot 91in advance of said bars. Disposed respectively over and under the tongue87, are an upper longitudinal pull bar 92 and a lower pull bar 93. Ahorizontal plate 94 overlies the slotted rear portion of the tongue 87and underlies the rear end of the pull bar 92. A bolt or other pivot 95passes through this plate 94, through the slot 98 and thi' ugh the rearends of the bars 92-98. Another bolt or other pivot 96 passes throughthe front ends of the bars 92-93 and through the slot 91, and the rearend of a third pull bar 97 is loosely connected with the bolt or thelike 95 so that it may freely swing ver-- tically according to necessaryrelative movements between the tractor or horse-pull and the machine. Toprevent lateral swinging of tractorpull bar 97 with regard to the tongue87, so that steering may be effected, I provide a vertically elongatedguide 98 depending rigidly from the front end of the tongue 87, andextending rearwardly from the lower end of this guide, is a bracebar 99.whose rear end is anchored by the pvot 89. Preferably, the portions87,--98-99 are formed by bending a single bar as shown, por- A tion 98being slotted to receive the pull-bar 97. Two rearwardly diverging bars100 are secured at their front ends to the plate 94 by bolts or the like101. By similar fastenings 102, these bars are secured to the bottombar. 38 of the vertical frame V, and the rear extremities of said bars.100 are volted or otherwise fastened at 103 to the side bars 34 of themain frame M. All pull on the tractor bar 97 or the horse evener istransmitted by the parts 96-92-93-95 to the plate 94 and all pullexerted upon the latter is transmitted by the bolts 10, the bars 100 andthe fastenings 108, to the mainframe M. There is thus no pull strainexerted upon the steeringbars 18 19 and consequently no tendency toinhorse tongue is horizontally swung. in one direction or the other, itcorrespondingly swings the stub-tongue 87 and the latter turns about thebolt 95 as a pivot, moving bar 18 in one direction and bar 19 in theother direction, thereby turning the vertical shaft 16 and the spindles15 to steer the wheelsV 14 inthe proper way. It is during the swingingof the stub-tongue 87 that the slots 90-91 come into play.

In'Fig. 12, some ohangesareshown overV the construction previouslydescribed. The frame 50a ccrrespondng to the frame 50, is forwardlyextended as at 50h. and is provided in advance of the angle bar 57a towhich the braces 64 are secured, with a second transverse'angle bar 57bto which braces 63a are secured, said braces 63a -1 taking the place ofthe braces 88 above described. Suitable clamps or the like 51a areprovided for securing the frame-extension .59h to the bars 52.

Another change which Fig. 12 shows over the preceding gures, is theprovision of'ardual feed hopper 23a instead of the two hoppers 23. Thishopper is provided with bottom-28b for guiding the seed to theseed-,dropping means 24.

Also illustrated in Fig. 12, is the provision which is made for hitchinghorses to the stubtongue 87. The upper reach of this stub-tongue isprovided with a stirrup 87a which receives a bolt 97a passing throughthe rear ends of two metal bars or arms 97`D which are secured to andproject rearwardly from the horse-tongue 97C,

said bars or arms 97b straddling the vertical portion 98 of saidstub-tongue 87.
